RF field strength meter
I make a RF simple field strength meter for test the remote control from doors ,alarm e.t.c at frequency VHF-UHF,
i used one μΑ meter ,2 diodes ,2 ceramic capacitors,a potentiometer,a box ,and one telescopic antenna.When press
the button at remote control,output there is small current RF,where with this simple circuit ,easy i can to know
if remote controls it work or no.
| Here it is the electronic design | Here it is the electronic material,without yet the potentiometer 47 Kohm, 2 capacitor 18 pF,2 diodes BAT 41,and a μA meter | Here it is the plastic box,i have open holes for μA meter ,and i have touch the telescopic antenna | ||

| Here with soldering iron the components it is ready | Here it is the sensitivity test | |||

| Here it the test with remote temperature /humidity sensor | It is ready | Ready with full open telescopic antenna | ||
